* ''Someday'' by Creator/IsaacAsimov manages this with no violence, no gore, no monsters, and no clear explanation of the title. Two kids own a low-quality robot that can tell fairy tales, and listen to some of its stories while discussing how crude it is compared to most modern machinery. Very little of what they're describing is advanced far beyond the present day. Then they leave the room, and the robot tells itself a story, one about a robot taken care of by cruel "step-people," a robot that one day hears the step-people talk of how advanced robotics is getting, and who knows now that someday... and that's when the robot seems to break down, for it keeps repeating the same word over and over. "Someday. Someday. Someday."
